To make a language lesson video for your class, teach one grammar point or eight to twelve words, not a unit. Open with a short story or scene that uses the target language in context, then name the rule in the learners' stronger language, then give examples one at a time, each spoken slowly, shown in writing and repeated once. Put only the target words on screen, never full paragraphs. Build in a pause where students produce the form themselves, and end by replaying the opening story so they hear it again with the rule in mind. Three to five minutes is enough. The explanation can be in English; the examples must be in the language being learned, and checked by a fluent speaker.

What makes a language video different

A history or science video explains content. A language video has to do two jobs at once: explain a rule, and give students enough clean, repeated examples of it to start hearing the pattern. Most language videos that fail do the first job and skip the second. They explain the rule well and then give two examples, which is not enough input for anyone to notice anything.

So the balance changes. In a science explainer, examples support the explanation. In a language video, the explanation supports the examples. Aim for at least as much time on examples and practice as on the rule itself. Students also need to hear each sentence slowly and see it written at the same moment, while the drawing shows what it means.

One point per video

If you need more, make a series. Short videos that each do one thing are easier to assign, easier to rewatch before a test, and easier to fix if one example is wrong.

The structure

The replay is the part teachers most often leave out, and it is the cheapest. It costs half a minute and turns the opening from a puzzle into proof that the rule works.

Worked example: the Spanish preterite and imperfect

This is one of the most common stumbling points for English speakers learning Spanish, because English often uses one past tense ("I read") where Spanish chooses between two. A four minute video for students who already know the present tense. The explanation is in English; every example is in Spanish.

The rule, in one sentence each

• The preterite is for completed actions seen as a whole, with a clear start or end: Ayer comí paella (yesterday I ate paella).
• The imperfect is for background, habits, descriptions and actions in progress: Cuando era niño, comía paella los domingos (when I was a child, I used to eat paella on Sundays).

Scene list

1. Hook story (Spanish, slow). Era un sábado. Hacía sol. Ana leía en el jardín. De repente, sonó el teléfono. Ana contestó. Drawing: a garden in sunshine, a girl reading, then a phone ringing, then her picking it up. Labels: only the five verbs.
2. Notice. "Five verbs, all in the past. But they are not all the same kind of past. Listen again to just the verbs." The verbs alone: era, hacía, leía, sonó, contestó.
3. The rule, imperfect. "The first three set the scene. What day it was, what the weather was like, what Ana was doing. That is the imperfect: background, description, something in progress." Drawing: a long wavy line under the garden scene.
4. The rule, preterite. "The last two are events. The phone rang, once. Ana answered, once. Each one started and finished. That is the preterite." Drawing: two short sharp marks cutting across the wavy line.
5. The picture to remember. "The imperfect is the film playing. The preterite is something that interrupts it." Drawing: the wavy line with the two marks, labelled imperfecto and pretérito.
6. Forms, -ar verbs. hablar: hablé, hablaste, habló against hablaba, hablabas, hablaba. Said twice, slowly. On screen: the two short columns.
7. Forms, -er and -ir verbs. comer: comí, comiste, comió against comía, comías, comía. On screen: the same layout, same colours.
8. Example one. Vivía en Madrid cuando conocí a Pablo. (I was living in Madrid when I met Pablo.) Said twice. Drawing: a long line for living, one mark for meeting.
9. Example two. Todos los veranos íbamos a la playa. (Every summer we used to go to the beach.) Drawing: a row of identical beach scenes. "Habit, so imperfect."
10. Example three. El verano pasado fuimos a la playa. (Last summer we went to the beach.) Drawing: one beach scene with a date. "Once, finished, so preterite."
11. Example four. Estaba cansada, así que me acosté. (I was tired, so I went to bed.) Drawing: a sleepy face, then a bed. "Description, then an event."
12. Practice pause. "Pause the video. Put these in the past: Hace frío. Llueve. Mi hermano entra." On screen: the three sentences, a countdown.
13. Answer. Hacía frío. Llovía. Mi hermano entró. "Weather is background, so imperfect. Your brother coming in is the event, so preterite."
14. Replay. The hook story again at the same slow speed, with imperfect verbs underlined in one colour and preterite verbs in another.

That is about 450 words of English explanation plus the Spanish examples, a little over four minutes once each example is said twice.

Notice what the script avoids. It does not list every use of each tense; a full list belongs on a worksheet. It does not introduce irregular forms beyond the ones in the examples (era, fuimos, íbamos), and it does not pretend the rule is always clean. Advanced students will meet sentences where either tense is possible with a change of meaning, and that is a good second video.

Pacing and repetition

Say each example twice. Once at a natural but slow pace, once again after a short pause. The second hearing is where most students actually catch the form.

Slow is not unnatural. Native-speed Spanish is too fast for beginners, but robotic word-by-word speech teaches the wrong rhythm. Aim for a slow conversational pace, with clear pauses between sentences rather than between words.

One sentence per scene. A scene with three example sentences becomes a reading exercise. One sentence, one drawing, said twice, then move on.

Keep the two languages visually separate. Target language in one colour, translations in another, always the same way round. Students quickly learn where to look.

Put the translation after the sentence, not with it. Show the Spanish, say it, give students a second to work out the meaning from the picture, then show the English. Translating instantly removes the moment of understanding.

What goes on screen

• The target words, large. The verb forms, the new vocabulary, the example sentence.
• Accents and special characters, checked. habló and hablo are different words. A missing accent on screen teaches the wrong thing. Generated text gets accents, umlauts and gender agreement wrong more often than English spelling, so pause on every scene with target-language text and check it letter by letter.
• Pictures that carry meaning. A drawing of a phone ringing makes sonó el teléfono understandable without English. That is the main thing a drawn video can do that a slideshow of sentences cannot.
• Nothing else. No full paragraphs, no grammar tables of all six persons unless that is the point of the scene.

Two languages in one lesson

A language lesson is the one case where mixing two languages in the narration is the point: the explanation in the learners' language, the examples in the target language. Before you build the whole video, make one scene with a Spanish example and listen to it. If the generated voice reads the Spanish with an English accent, or reads the explanation with a Spanish one, you have two clean options.

Record the target-language lines yourself, or ask a native-speaker colleague. You can replace the generated voice with your own recording. For a language class this is often the better choice anyway: students hear their teacher's voice and a real accent.

Or make two projects from the same script. One with the explanation and examples narrated in English for the grammar, and a second project from the Spanish parts only, narrated in Spanish, for listening practice. The two-project approach, and how to keep them matched scene for scene, is covered in how to make a video in two languages at once.

Either way, a fluent speaker should watch the final version once. Fluent speakers catch the things a careful learner misses: a word that is correct but sounds old-fashioned, a regional form your students will not use, a sentence that is grammatical but nobody would say.

When students make the video

A language lesson video is also a strong student task, especially at A level or the equivalent. Making a short video that teaches a grammar point to younger students forces the maker to understand the rule well enough to choose clean examples, which is harder than doing an exercise. Give them the six-part structure, ask for six examples they wrote themselves, and require a fluent speaker's check or a peer check before submission.

Make it

1. 1

   Choose one point and write the rule in two sentences

   One sentence for each form or each half of the contrast. If it needs a paragraph, split the topic into two videos.

2. 2

   Write a short hook story that uses both forms

   Five to seven sentences in the target language, simple vocabulary, every target form appearing at least once. Check it with a fluent speaker.

3. 3

   Write six to ten examples, one per scene

   Each with a drawing that shows its meaning and a translation that appears after the sentence. Mark each example to be said twice.

4. 4

   Paste the script into openCanviz

   Choose Keep my wording so every example is spoken exactly as written, set the target length, and pick whiteboard or doodle style so the pictures carry meaning without clutter.

5. 5

   Listen to one example scene before going further

   If the target-language lines sound wrong, record them yourself and replace the generated voice, or narrate the Spanish parts in a second project in that language.

6. 6

   Check every accent and form on screen

   Pause on each scene with target-language text and check it letter by letter against your script. Fix any scene in the editor.

7. 7

   Add the practice pause and the replay

   A scene where students produce the form before the answer appears, and the hook story again at the end with the forms highlighted.

Common questions

How long should a language lesson video be? Three to five minutes for one grammar point or one small vocabulary set. Longer videos get skipped through, and in a language video the skipped parts are usually the examples, which are the parts that matter.

Should the whole video be in the target language? For advanced classes, it can be. For beginners and intermediate students, explaining the rule in their stronger language and keeping the examples in the target language usually works better. The rule is easier to understand, and the examples are where the language input comes from.

How many new words can one video teach? Eight to twelve, each shown with a picture, said at least twice, and used in a sentence. More than that and students remember the first few and the last one.

Can I use this for a language that is not written in the Latin alphabet? Yes, but check every on-screen word especially carefully, since drawn text in some scripts can come out wrong. Keep on-screen words few, and show transliteration only if your course uses it.
